# Fix man page locations:

# I must confess that I haven't looked for the cause because I have more
# pressing things to do at the moment.

# Enter the package's root:

# Ditch the new host keys, since these have to be uniquely prepared on each machine:
rm -f etc/ssh/ssh_host_dsa_key
rm -f etc/ssh/ssh_host_dsa_key.pub
rm -f etc/ssh/ssh_host_rsa_key
rm -f etc/ssh/ssh_host_rsa_key.pub
rm -f etc/ssh/ssh_host_key
rm -f etc/ssh/ssh_host_key.pub

# Set up the config script installation:
mv etc/ssh/ssh_config etc/ssh/ssh_config.new
mv etc/ssh/sshd_config etc/ssh/sshd_config.new

# Add the init script:
mkdir -p etc/rc.d
install -vpm755 $CWD/rc.sshd etc/rc.d/rc.sshd.new

# Add the pam stuff:
mkdir -p etc/pam.d
install -vpm644 $CWD/sshd.pam etc/pam.d/sshd.new

# Patch the init script.  To generate a DSA SSH key gen takes about 5 minutes
# on a RiscPC and new users may think the bootup has hung.

# Set generic Slackware packaging policies:
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # set all files to root.root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh
slackmp         # run makepkg -l y -c n

# Perform any final checks on the package:
cd $PKG
